Water tank depth sensor arduino.

Theoretically when the sensor is not in the water the measured value at the sensor pin is approx 1 0855 v which would be equivalent to 1347 bits. The arduino then reads the output of the transducer and reports the depth of the tank. Download learn arduino sensor with projects for beginners by james conner.

The ping sensor measures distance using sonar. Yeah there is a way just using an ultrasonic sensor this is very simple where the level of water is measured using ultrasonic sensor which gives the depth by determining the tank depth we can set the maximum and minimum level. The arduino then reads the output of the transducer and reports the depth of the tank. In this project we will use an ethernet shield to have the arduino connect to an online datalogging service called pachube to generate graphs of water depth over time but you could also have it make decisions on the basis of the reading to control items such as a water pump or irrigation system solenoid.

When water has been pumped into the tank up to the point that thesensor measures a distance of 14cm the red led comes on again as water keeps filling up the tank and gets to the point the sensor measures 8cm the blue led comes on finally when water gets close to the brim of the tank where the sensor measures a distance 3cm the white led. In this project we will use a wishield that provides wifi network connectivity to report the current water level using a web interface. An ultrasonic well above human hearing pulse is transmitted from the unit and distance to target is determined by measuring the time required for the echo return.
